Application for m me filed .ranu'u 11 1927. Serial No. 150,513.

' The purpose of this invention is to provide a portable outfit forcleaning and sorting or grading grain,the apparatus shown being especially designed to handle beans. It consists of certain features and elements of construction and invthe combination ofparts hereinafter described and shown 'in'the drawings as indicated .by the claims. I

In the drawings Figure l'is a side elevation partly in section showing a vehicle carrylng a power plant and machinery adapted to be driven thereby for'cleaning andsorting grain in accordanee with this invention.

Figure .2 .is a somewhat diagrammatic transverse section taken as. indicated. at line 22 on Figure 1.

In accordance with the present practice the beadgrowerdr farmer harvests his crop by cutting the vines and then passingsthem through a threshing machine designed to separate most of the estalk and leaf. material from the beans themselves. The output of the threshcr however; contains considerable 'dirt, some chafi and a varying proportion of vbeans not suitable forimnrket at the highest price because of roughness or irregularity in shape. This mintureof beans and dirt musty. therefore he further :treated and ordinarily such additional cleaning and sorting is can onv at a. fiorage elevator and the farmer is charged back for the work of cleaning and sorting his icular lot of beans in accordance with t e weight of refuse material culled therefrom. He must first load the output of the thresher intorsacks and then transport it, usually several miles, to the elei vator where the acks are dumped into bins or ho ers leading to the various mechanical devic s for cleaning the beans. The final sorting or picking as it is called, may be .done by hand or by means of machinery such as a centrifugal picker of the type shown in my pending app After the sorting or grading'operation the beans are again bagged and or for it instead of being neccssaril' limited to the particular elevator in is -Vl0ll1- ity, thefipresent invention provides a portable'out t'which can be taken to the grower-s the ication, Serial No. 393,385.

The apparatus may be mounted upon a motor truck, a trailer, or a horse-drawn vehicle as desired but as illustrated in Figure 1, 'I have chosenfto show the vehicle as a motor truck of a familiar type having a minternal combustion en 'ne, 1, carried at the forward end of its mine, 2-, and adapted to drive the vehicle through the usual propeller-shaft, 3, extending to suitable gearing associated with the rear wheels, 4, Jour-v naled in brackets, 5, which are secured tothe frame, 2, is a powermembemshown asa counter-shaft, 6, adapted to be driven by a belt, 7, from a pnlle 8, on the forward end of the crank shaft of the engine, 1. From this countershaft, 6, it is therefore possible mg the beans. It may be understood that not shown, or when the vehicle is traveling and it is not desired to run the eleaning machinery the belt, 7, may be simply. slippedoif from the pulle 8, so as to disconnect the countershaft entirely from-the engine. Obviously the vehicle is of the horse-drawn type instead of being self propelled, it will still be necessary to provide an engine carried on the vehicle frame for driving themachinery. thereon power pulleyjrom which power'niay be derived from some other prime mover stationed adjacent the vehicle. Srich an arrangement would be a simple and obvious modification of that shown in Figure 1' and specific illustration of it is deemed unneces- Just back of the engine, 1, there is mounted-on the frame, 2, a cleaning machine com- 100 prising a receiving hopper, 9, having a gate or valve, 10, controlling the flow of beans therefrom to the inclined screen, 11, direct- 1y below. The screen, 11, is sufliciently coarse to permit the through it while the coarse tailing and straw travel by gravity over the screen and ,are carried off through a spout, 12, dischargmg at one side of the vehicle. A second screen, 13, below the 'first receives the ma- 110 to secure power for driving the machinery carried by the truck for cleaning and s'ortpulley, 8, may be operatively connected or at least to provide a 4 good stock to pass terial for. further gradin This is a fine screen dust to pass through it beans merely to roll down it toward an and sit ting. permitting sand and opening, 14, in a vertical air-shaft," 15, leading from a fan or-blower, 16, to a discharge hood, 17. The heavy sand and dust eliminated by the screen, 13, falls through a port, 18, of the inclined chute, 19, and discharges through a spout, 20. The dust re 'maining with the beans and entering the opening, 14, tendsto be carried away in the air blast passing out through the hood, 17,

.while the beans themselves, being much 'vator is shown but it may be understood to be of the'same familiar construction as the elevator, 24, mounted at the opposite side of the frame, 2, and seen in Figure 1 as consisting of an endless belt, 25, fitted with a series of cups or buckets, 26, which pick upthe beans from the boot of the elevator I at the lower limit of belt travel and dis-,

charge them as the belt traverses the head pulley. For convenience both elevators are connected together by a common drive shaft, 27 for their respective head pulleys. The beains'discharged over the head pulley of the elevator, 23, are received in a chute, 28,

. which'leads ,to the hopper, 29, of a centrifu al sorting or (picking machine ofthe type a ove mentione Asindic'ated in Figure 1 the rotary fan or blower, 16, is driven by a belt, 30, from a shaft, 31, which in turn is driven by a belt, 32, traversing a pulley, 33, on the countershaft, 6. An eccentric, 36, on the shaft, 31, incidentally. operates a vibrating device for the sand, chute, 19, and screens, 11 and" 13, of the cleaning machine,

In the picking machine the beans arriving in the hopper, 29, are fed outwardly therefrom through ports, 34, and are carried by centrifugal force radially downward across pairs of rubber-faced and cooperating rollers, 35, through which the rou h beans ,or particles .of dirt are passed means of frictional engagement which the rollers exert upon'them, while the smooth good beans are discharged through spouts, 36, leading from the outer ends of the rollers into a receiving hopper, 37. The principle of this type of machine is well understood and is more fully described in my said pending application, Serial No. 393,385. The

culls and dirt removed by the picking rollers, 35, fall into a hopper, 38, and are dis-- charged through a spout, 39, from which y y be collected if any further use i tobe made of them.

The hopper, 37, discharges into a final ut allowing the good at 40, journaled to revolve in a tubular casing, 41, of perforated sheet metal. The 'rooveof the core, 40, is fitted with brush ristles, 42, so that as the beans are picked up by the spiral grooves at one end of the device and fed toward the other end as the core, 40, rotates, they are brushed and scoured by the bristles, 42, which thus :remove practically all dirt or dust which may have adhered to the beans even through the other cleaning processes and thiQdust passes out through the perforations ottheenclosing tube, 41, whence it is collected in a casing, 43, and discharged through aspout, 44, leading therefrom. The brushed beans ar .riving at the further end of tliefrotating core, 40, are discharged into a Spent, 45,

which is preferably of twin construction provided Witha valve, 46, for directing the eans into one spout or the other for. loading them into bags.

As will be seen from Figure 1, the centrif- 'ugal picking machine is driven by a belt,

To facilitate the,'loading ofthe beans into the receiving hopper, 9, thebutfit may be provided with'the elevator, 24, above mentioned. As shown in Figure 2, its'receiving' boot, 52, opens at the outer side where it is provided with a hopper, 53, into which the eans and dirt to be cleaned and sorted may be dumpedfrom bags or fed directly from the bean threshing machine. Preferably this hopper, 53, is designed to collapse against the side of the boot 52, by folding about a hinge, 54, so as to come within the lateral dimensions of the vehicle when the apparatus is being transported from place to place. From the upper end of the elevator, 24, the beans picked up by it are discharged to .an inclined chute, 55, into the hopper, 9, of the cleaning machinef I claim 1. In combination with a vehicle and a power member mounted thereon, apparatus mounted on said vehicle adapted to receive threshed grain and including mechanism for separating out chafl and dirt, mechanism for separating rough imperfect grain from smooth grain, and mechanism for polishing and cleaning the grain, means for conduct ing the grain from each mechanism to the next and driving connections from said power member adapted to operate all said apparatus simultaneously.

2. In combination W1 th a vehicle and a power member mounted thereon, apparatus assembled on said vehicle including a fanning mill for cleaning grain, apicking or sorting machine for grain and a grain polishing machine together with conduits for leading the grain from each machine to the next and driving connections from said power member to said apparatus.

3. In the combination defined in claim2,

an elevator mounted on the vehicle with its,

receiving boot near the ground and provided with a discharge spout at its upper end arranged to feed material to the fanning mill.

4. In the combination defined in claim 2, an elevator mounted on said vehicle and a chute leading from the-fanning mill to the receiving boot thereof, the upper endof said elevator beingprovided with a discharge spout arranged to feed material to the pick ing machine.

5. In the combination defined in claim 1, the polishing. mechanism being-arranged to receive. material from the mechanism for separating the rough and smooth grain and being provided with a discharge s out conveniently near the ground for fil 'ng bags with the; polished grain.

v6. In combination with a vehicle and a 25 power. member mounted thereon, apparatus assembled on saidvehicle including a fanning mill for cleaning rain and a grain sorting or picking mac me, both having grain receiving hoppers at substantially the 0 same level and both being. arranged to dis charge the grain downwardly by gravity, an

elevator connected to receive material 'released by gravity from the fanning mill and carry ceivmg hopper of the picking machine together with driving connections from said power member to said machines and elevator.

7 In the-combination defined in claim 6,

an additional elevator on the vehicle having itsreceiving chute adjacent the ground and a spout arranged to discharge into the receiving hopper of the fanning mill.

In testimony whereof, I have hereuntoset my hand at Detroit, Mich, U. A., this 10th day of January, 1927.
